Voice commands for Playback Speed adjustment

[dkBrazz]

There is no way to adjust the playback speed in CarPlay without picking the phone There is also no possibility to add controls into the CarPlay screen - #509 So there will be useful Siri triggers for voice commands

My suggestion is: "playback speed up", "playback speed down" - increase/decrease to the closest value according to the application scale of speeds "sat playback speed to X.XX" - sets the exact playback speed

🤔 yeah thad could be useful as well to add it to our url scheme actions, as a side note, for CarPlay I've noticed that there's a playback rate button which toggles speed:

I can't find the proper docs regarding that option though to enable it for BookPlayer as well, if anyone can, please let us know

I found it! MPChangePlaybackRateCommand, implementing this in the AppDelegate alongside the other commands for MPRemoteCommandCenter should enable the speed toggle from CarPlay (maybe from the locked screen as well?)

This is just great!

I reopened #509 - @GianniCarlo is a wizard 😯
